largely tipped with white; upper surface of the wings grey, their 
under surface white; bill leaden grey, darkest at the tip; feet 
blackish brown. 
Total length 6? inches ; bill 2; wing 42; tail, 3; tarsi 2. 
Hab. Central Australia. 
Remark.—This large and fine species is unlike every other known 
member of the genus. It is most nearly allied to 4. albiventris, but 
differs from that bird in the jet-black colouring of its under tail- 
coverts, and from A. cinereus in its smaller size and the greater 
extent of the black on the face. The specimen from which the 
above description was taken has been kindly sent to me by Mr. S. 
White, of the Reed-beds, near Adelaide, South Australia, who 
informs me that it was shot by him at St. Becket’s Pool, lat. 
28° 30’, on the 23rd of August, 1863, and who in the note accom- 
panying it says, ‘‘I have never seen this bird south. It collects at 
night, like 4. sordidus, and utters the same kind of call. It seems 
to be plentiful all over the north country. I saw it at St. Becket’s 
Pool, feeding on the ground, soaring high in the air, and clinging in 
bushes, like the others. The two sexes appeared to be very similar 
in outward appearance. The stomachs of those examined were 
fleshy, and contained the remains of small Coleoptera. 
2. ON SOME RECENTLY DISCOVERED BoNES OF THF LARGEST 
KNOWN Species oF Dopo (Dipus Nazarenvs, Barrurrt).

The three bones which I now have the pleasure of exhibiting 
have been recently received by me from my brother Mr. Edward 
Newton, a Corresponding Member of this Society, who himself found 
two of them in a.cave on the south-west side of the island of Ro- 
driguez, which he visited on the 2nd of November last. The third 
was obtained on the same island, about the same time, by Captain 
Barkly, a son and aide-de-camp of the Governor of Mauritius. All 
three belong, without doubt, to the largest known species of Dodo, 
to which Mr. Bartlett (P. Z. S.1851, p. 284) applied the name Didus 
nazarenus, and which was so unaccountably overlooked by Messrs. 
Strickland and Melville in their excellent monograph of the curious 
group Didine. These authors, as Mr. Bartlett showed (loc. cit.), did 
not distinguish between this very large bird and the smaller and more 
slender “ Solitaire” (Pezophaps solitaria), which, if we are to trust 
the evidence before us, was, equally with Didus nazarenus and D. 
ineptus, an inhabitant of Rodriguez. 
The two bones found by my brother were picked up near the en- 
trance of a very dry cave, where little, if any, stalagmitic deposit was 
forming, at least at the time of his visit. One is a perfect left tarso- 
metatarsus, and the other a left humerus, wanting its extremities, as 
is so often the case in specimens of this bone found under circum-
